Breast Aug
The morning of my surgery I was 131lbs. I had 7 lbs of skin removed with my lbl and about 1.5lbs of implants put in. When I came home from the hospital I was 138 lbs. About a week later I was 124lbs. Now 9 weeks later I am 127lbs. So yes, I would say what you are experiencing is normal.

Yes, gaining weight after surgery is not a big concern. May be this weight gain is due to the swelling in the treatment area. There are some exercises with the help of which you can advance your recovery. You need to ask your surgeon for the exercises you should do and the ones you shouldn’t do, because in breast augmentation surgery, you have some restrictions due to your wound and suture's.
